Prepar3D v4 Wont Launch, New Install. ai_player.dll api.dll

Postby mattlm0831 » Tue Aug 21, 2018 7:21 pm

Hey all,

This is a new Install.

I just downloaded the sim for the first time and I am trying to get into it and every time, besides once, it crashes without making it to the main menu. I have gone through the debugging guide and have tried everything multiple times, re installed 2 times, deleted game files 3 times, unplugged all of my hardware etc. All drivers are up to date, all software is up to date.

1. Version 4.3
2. Windows 10, up to date
3. No add-ons
4. i7-4790k, GTX-980, Corsair Vengeance RAM
5. No overclocking, all parts run at manufacturer settings
6. No change to prepar3d as I haven't even run it once.
7. I have several messages I can supply:
Faulting application name: Prepar3D.exe, version: 4.3.29.25520, time stamp: 0x5b2c3263

IT WORKS!!!! SO HAPPY!!!

Looks like it was the codec issue with the FL Studio codec. How strange!

Thank you so much I appreciate everything immensely.
